Many Chinese medicines are metabolized by the liver, and excessive dosage or use of more toxic Chinese medicines may damage the liver. Some Chinese medicines are relatively mild in nature, so as long as they meet the indications for Chinese medicine, and the dosage is small or the duration of use is too short, they generally will not damage the liver, and seldom have the uncomfortable reaction of hepatic impairment. However, it should be noted that, unless following the doctor’s instructions, long-term use of the drug is generally not recommended, so as to avoid liver damage due to excessive dosage; or long-term use of bitter and cold drugs, such as gentian herb, bitter ginseng, etc. may also cause liver damage; or the use of more toxic drugs can also cause liver damage, such as epiphyllum, white fruits, raw herbaceous woo, gall bladderwrack, etc.. When liver injury occurs when taking Chinese medicine, timely medical consultation is needed. Drugs should be used in accordance with medical advice.
